Athletic sock



FIG. 1 is a rear perspective view of an athletic sock showing my new design;

FIG. 2 is a side elevational view, the opposite side being a mirror image thereof;

FIG. 3 is a front elevational view thereof;

FIG. 4 is a rear elevational view thereof;

FIG. 5 is a top plan view thereof; and,

FIG. 6 is a bottom plan view thereof.

The shading on the two parallel lines on the rear of the sock depict a contrasting color to the remainder of the sock. 

I claim the ornamental design for an athletic sock, as shown and described.
